--TRUMP THINKS FACEBOOK COLLUDED WITH MEDIA AGAINST HIM: President Trump on Wednesday seemed to suggest that Facebook had colluded with the news media against him during the 2016 presidential race. The president's comments come after the social media platform told investigators it discovered that thousands of political ads published on its platform over the past two years were linked to fake accounts based in Russia. "Facebook was always anti-Trump.The Networks were always anti-Trump hence,Fake News @nytimes (apologized) & @WaPo were anti-Trump. Collusion?" the president tweeted. He added: "But the people were Pro-Trump! Virtually no President has accomplished what we have accomplished in the first 9 months-and economy roaring."

--MORE PROOF RUSSIA IS TAKING ALL OF OUR ENERGY: The chair of the House Science Committee is investigating whether Russia has purchased advertisements on Facebook and other platforms to influence the U.S. energy market. Rep. Lamar Smith (R-Texas) is pressing Facebook, Twitter, and Google for information and documents on any Russian entities that have purchased anti-fracking or anti-fossil fuel ads. The letters are part of the committee's broader oversight of "what appears to be a concerted effort by the Russian government to influence the U.S. energy market," Smith wrote in letters to the tech giants' CEOs this week. "In light of Facebook's disclosure of over $100,000 in social media advertising associated with Russian accounts focused on the disruption and influence of U.S. politics through social media, it is likely that Russia undertook a similar effort using social media to influence the U.S. energy market," Smith wrote. The Republican chairman is looking for any and all information "regarding Russian entities purchasing anti-fracking or anti-fossil fuel advertisements or promotions" dating back to 2010.

NEW FBI CHIEF ON 'GOING DARK:' In his written testimony for a Senate Homeland Committee hearing Wednesday, new FBI head Christopher Wray reiterated the FBI's long-held stance that tech companies use of strong encryption is a key problem for the Federal Bureau of Investigation. It was a reversal from the position he took at his July hearing, when he called for "balance" between civil liberties and security.

"[W]e are seeing more and more cases where we believe significant evidence resides on a phone, a tablet, or a laptop -- evidence that may be the difference between an offender being convicted or acquitted." Wray wrote.

"Some observers have conceived of this challenge as a trade-off between privacy and security. In our view, the demanding requirements to obtain legal authority to access data -- such as by applying to a court for a warrant or a wiretap -- necessarily already account for both privacy and security," he later added.

Under former chief Jim Comey, who deemed encryption's thwarting of investigations "going dark," the FBI asked lawmakers to mandate some mechanism to circumvent device security for use when the FBI had a warrant to investigate a device.

Former CIA and NSA head Michael Hayden, a House working group on encryption, nationally recognized encryption experts and others argue that so-called "backdoors" are hazardous for reasons that have nothing to do with civil liberties. Instead, they argue, creating backdoors introduces new ways for hackers to steal data.

STATE VOTING SYSTEMS: The Department of Homeland Security (DHS) said Tuesday that it made an error when it notified the state of Wisconsin that Russian hackers scanned the state's voter registration system.

The Associated Press reported that the agency initially thought hackers accessed systems operated by state election officials, but told those officials Tuesday night that hackers instead accessed the state's Department of Workforce Development.

"Based on our external analysis, the WI IP address affected belongs to the WI Department of Workforce Development, not the Elections Commission," a Homeland Security official wrote in an email.

A member of Wisconsin's Elections Commission expressed outrage to the AP in an email, accusing the Trump administration of possibly organizing a cover-up.

"Either they were right on Friday and this is a cover up, or they were wrong on Friday and we deserve an apology," Elections Commission Chairman Mark Thomsen said.
